Referring to the accompanying drawings, I have used the referencenumeral 10 to indicate the frame of the baler, having bearings ilat itsforward end, in which is mounted speed reducing gearing mechanism of theordinary type. Said speed reducing mechanism includes a drive shaft 12,one end of which is provided with a pinion 13 designed to drive a spurgear 14 mounted on a shaft 15, which is also rotatively mounted in thebearings 11. The shaft 15 is provided with a pair of pinion gears 16,which are in mesh with the spur gears 17. One of the gears 17 is mountedon a shaft 18, and the other on a shaft 19. The shafts 13 and 19 are incommon alinement, and the gears 17 connected by a wrist pin The balerisprovided with side members 21, a top 22 and a bottom 23. The body ofthe baler is divided into a feed chamber 24, and a baling designed tooperate in the feed chamber in the usual manner. Said plunger isoperatively connected with the wrist pin 20 by means of a connecting rod27. The sides of the baling chamber are provided with openings 23 and 29for the `purpose. of permitting the tying'mechanism to be moved into andout of the feed chamber,

as hereinafterf described.

, The sides of the baling chamber are provided with horizontal slots 30extending from the forward end of the baling chamber to its rear end,andin communication rat their forward ends with vertical'grooves 31.Said grooves 31 are formed in channel bars 32 secured to the sides ofthe baler and extending above the baler a considerable distance, asillustrated in Figure 2. The channels 32 are provided for the purpose ofassisting in automatically handling the division blocks 33;.' theconstruction and operation of which are as follows: l

This part of my invention is best illustrated in Figure 30 is a sideelevation'of `one* member- Figures 2) 81'9f 10 11 121 13 17 and 1'8- Thedi' lface of the plate 34 is provided with a block 35 having wirereceiving grooves 36. The grooves 36 are spaced apart a distance equalto the spacing of the slots 30.

. The back ofthe plate 34 is provided with a vertical angle 37 securedadjacent to each end of the plate 34, said angles being provided withhorizontal shafts 38 and 39, the shaft 39 being longer than the shaft38. The outer ends of both of said shafts are designed to travel in thegrooves 31 when the block isrmoved to position in the baler, and `tortravel in slots 30 as the block is moved rearwardly through the baler.The ends of the baler a slight distance, as illustrated in Referring toFigure; 8 it will be seen that notches 40 arevprovided in the backflanges of the channels 32 to permit the ends of the shaft 38 toenterthe slots 30, and notches 41 are provided to permit the shaft 39 toenter the lower slots 30, the notches 41 being deeper than the notches40, so that asthe division block is lowered into position, the ends ofthe Shaft 39 will not enter the notches 40. Spring actuated pawls 42 areprovided which engage the sha-ft 39 and lock the division block againstupward movey ment after it has been lowered into position.

After the block has been placed in position within the feed chamber, itis fed rearwardly by the movement of hay or other material being fedinto the Daling chamber in the usual manner until a given block hasreached the rear end of the baler. The block is then delivered to theup- -per endvof the groove-S81 by the following inechy anisrn:

Mounted transversely above the forward end ofthe baling chamber is ashaft 43 mounted in suitable bearings 44. Said shaft is provided at eachend tif-ith sprockets 45.

Secured to each of the channel members 32 is a bracket 46 provided-witha sprocket 47. Each of the side members of the baler is provided with anupright post 48 in which is mounted a sprooket `49. A sprocket50`ismounted in a suitable bracket 5l fixed to the rear end of thebaler. An extension franie52 is provided which also carries sprockets 53and 54.

Thefrarne 52 is provided with channels 55 which guider the ends of theshaft 39. The upper ends of the channels 55 terminate in forwardly andupwardly extending channel members 5,8, which have their forward endscurved to receive the sprockets 47, as illustrated in Figures 2 and 12.The lower ends of the channels 55 are in aline-nient with the rear endsof the slots 30.

rlhe frame member 52 and the uprights 48.

also carry channel members 57, having their loi-,verende in aline-mentwith the upper ones of the slots The channels 57 are designed to receivethe ends of the shafts 38. The forward ends of the channels 57 aremounted in such a manner as to deliver the 38 to the upper surface ofthe channel 56 in the manner illustrated in Figure 17. The shafts 38 arecarriedv by a flange 58 secured to the inner edge of the channel 56,said iiange being ilustrated in Figures 9 and 13.

.Each set of sprockets 45, 47, 49, 50, 53 and 54 is designed to supportya chain 59, said chain being provided with outwardly projecting lugs 6G,sa. lugs lo secured to the inner edge of the chain links, as illustratedinFigures 10 and 11.

plane slightly outside of the sides of the baling press in such a mannerthat as the shaft 38` reaches the rear end of the lower slot 3i), thesaid shaft will be engaged hy one of the lugs 60, as the chain 59 isoperated in a clockwise direction, as shown in Figure 2. The shaft 39will then travel in the grooves of the channels 55 and the shaft 38 ofthe given block will travel in the grooves of the clionnels 57. Theychains 59 move Said blocks through the channels.

The block nrst assumes the position A as illustrated in Figure Eloydotted lines. The block is then moved to the position B, and thence toposition C, and finally delivered to the grooves- Si of the channels 32,in the manner illustrated in .Figure i2. it will he seen that as theblock travi-ils,freirA the position B to the position C it is inverted,so that the block is always fed vto the feed chamber with the grooves36in the forward face of the block.

As the block is delivered to the slots 31, the shaft 39 restson springretained arms 6l, with both of the shafts 38 and 39 within the slots 3land the lower edge of the 'olock slightly above the upper side of thefeed chamber, as illustrated in Figures 8 and 17. It will be seen byreferring to Figures 2 and 17 that the sprockets 45 and 47 are somounted that the chains 59 move downwardly and rearwardly from thesprockets 47 in such a manset of sprockets is mounted in a corninon tion8l engages thev roller 79,

ner that the lugs 60- are caused todisengage the shaft39 as the saidshaftis moved-into the slots 3l: Slots 62 are providedlin the rear edgesof the channels 32 to permit the lugs 60 to enter said -channels as thelugspass over the sprockets 47.

0n account of the shaft 38 being shorter than f the shaft 39, the endsof the shaft 38 will not be continuously rotated and any. blocks being`moved to the deliveryend of the saler will be moved upwardly and thenforwardly to slots 31,

In ractual operation three blocks are usedtwo of which are always in thepaling chamber-while 'A the third is normally supported by the members61.

the outer'end of the shaft i9 ,a nevell gear 63 fixed to said shaft. Theouter `end. ofthe nhaftv 43 is provided with a bevel gear 64 in mesh h`a pinion krnounted on an inclined'shaft 51S, rotatively mounted insuitable hearings, The for" ward end of theV shaft is provided with apinion 67 in mesh with the bevel gear 63; l

For forcing the blo into 'the `feed chamber l have slidably mounted inthe upper end oi the grooves 3i a plunger 68, best illustrated inFigurel 8 and 17. Each end ofthe plunger 88 is provided with anupwardly-extending member 69, designed to travel in the grooves31.-Pivotally secured to the inner edge of each of the members 69 isalink 70. The free ends of the links 70 are pivotally connected toupwardly and forwardly extending arms l'lirigidly secured 'to a rockshaft 72. Said shaft` 72 is mounted in suitable hearings carried by anupright 73,- on the sides of the baler. A rock arn174 is mounted on oneend of said shaft 72, said arm being actuated by .a cam on the cam shaft76, said shaftbeing vated position with the rol-ler 79 in engagementwith the cam 75, as illustrated in Figure fl-il.-

- Itwill bessen that as the shaft 75 is rotated,

the cam V75 will be rotated unt? the arm 78 to he lowered, and in turnthe free ends of the arms 71 loweredI which will cause the plungerV 68to engage the upper edge of the lolock re-sting on the meinber 61, andthe blockinoved downwardly against the resistance of said member 6l toposition within baling chainber, with thek shaft 39 beneath. the pawls42.

The plunger 68 is then. allowedto return to its normal position, afterwhich a second-block may be moved plunger. l A

By this arrangement itw'll he. seen that I have provided a simpleniechan which will automatically return the 1docks to an operativeposiinto. position beneath said tion, where they may be held andretained, and

provided with nieans whereby the hlock will be automatically fed into'position after the tying operationk has been completed, as hereina.fterdescribed.

The cam shaft 76, together with other auto- For rotating the shaft 1have mounted on -said blocks beinginverted during said movement.

matic timing mechanism is operated asV follows: Rotatively mountedbeneath the frame 10 in suitable` bearings is a shaft 82, having oneendy.provided with a gear 83 designed to mesh with a pinion 84rotatively mounted on the shaft 19. The outer face of the pinion 84 hasa hub 85 provided with a single notch 86 for receiving a lug 87 cf aclutch member 88, said clutch member being feathered to the shaft 19 asillustrated in Figure 3.

The clutch member 88 is actuated by means of 'a rock arm 89 having afork 90 at one end. Pins 91 are carried by the forks 90 designed to`enter a groove 92 in the clutch 88.

A spring 93 is provided for normally applying an inward pressure to theclutch 88. The arm 89 is provided with flanges 94 for slidably receivinga trip block 95. The inner face of said block ,95 has an inclinedportion 96 and aat portion The outer face of the spur gear 83 provideswhat I shall term a master cam, the periphery of said cam being providedwith a lug 98 designed Ato engage the inclined portion 96 of the block95,

to be disengaged from the notch 86. The clutch 30l nember is thrown intooperative position by moving the tripv block 95 rearwardly, or to theleft asshown in Figure 3.

This trip block is actuated by means of a rod 99, which has one endconnected to the block 95, and the other end connected to a downwardlyextending arm 100. The arm 100 is pivotally connected to a plate 101carried by the frame of the baler, The free end of the arm 100 is de-,.signed to be engaged by an angle 102 mounted on what I shall term atension plate 103. Said arm 100 is yieldably supported forwardly bymeans of an expansible spring 104, so that as the plate 103 is movedrearwardly, after a bale .oi predetermined size has been formed, the

member 102 will then engage the lower end of the arm 100, swinging thesaid arm rearwardly and the block 95 rearwardly, thereby setting the cam83 into operation.

. In this connection it will be seen that the pin-v ion 84 is mounted onthe shaft which operates -the plunger 26. The pinion, therefore, isoperated in unison with said plunger.

By providing a single lug 87 and notch 86, the

clutch 88 will be moved into operative position r nly at the time theplunger 26 is at its rearward position of movement.

If the block 95 should be tripped before the plunger has reached thisposition, the lug 87 will engage the face of the hub and travel an saidface until the said hub has rotated to with the notch 86 in alinementwith` position the lug 87, after which the said lug will enter the notchby the action of the'spring 93.v

The rear end of the baler is provided with the isual tension device 105,which consists of a rod 106 tired to the lower frame members of thebaling chamber and slidably mounted in a bearing 107 secured to thecentral side plate 108. The upper end of the rod 106 is slidably mountdin a bearing 109 secured to the upper frame member. The upper end ofeach of the rods 106 is screw threaded and provided with nuts 110 andsprings 111 whereby the bottom andy Vmounted. on pins 119.

baler is somewhat contracted. This provides means for offeringcomparatively high resistance to the material as it moves through thebaler, which resistance may be varied by adjustment of the nuts 110,thereby providing means for varying the size, as well as the density, ofthe bale.

For throwing into operation the ymaster cam, and for taking up slackwires of the bale, after the wires have been tied in the .mannerhereinafter described, I have provided what I shall term an auxiliarytension device.

Said auxiliary tension device consists of the plate 103 slidably mountedadjacent to each side of the baling chamber, said plates being slidablymounted on guide rails 112 secured to the bottom and top frame members.The lower edge of each of the plates is provided with bearings 113slidably mounted on the lower rods 112, and slotted bearings 114slidably mounted on the upper rods 112. The bearings 114 are slotted topermit the bottom and top members to be moved toward and from each otherby the tension device 105.

The inner face of each of the plates 103 is provided with a pair ofslidabl'y mounted dogs 115, best shown in Figure 19. The forward end ofeach of the plates is provided with inclined slots 116, slidably mountedon pins 117 supported in the plate 103. The rear ends of the dogs 115are provided with curved slots 118 slidably The dogs are placed in adiverging manner as illustrated, with their apex ends provided withinterlocking teeth 120, so that both of said dogsl may be operated inunison.

The forward ends of the dogs 115 are so mounted as to be engaged by theends of the shafts 38 and 39, as the division block travels through thebaling chamber, andl designed to disengage said shafts` and pass betweenthem when said dogs have reached their rearward position of movement,relative to the plate 103.

-Pivotally secured to the back end of the upper dog 115 ie a pair oflinks 121, the outer one o! which is pivotally connected to the innerface of the plate 103, as illustrated in Figure 2, to form a togglejoint for locking the dogs 115 in their open position.

The plate 103 is provided with a slot 122 through which a pin 123extends. One end of the pin 123 forms a pivot between the links 121, andthe other end is connected to a vertical link 124. The lower end of thevertical link 124 is pivotally connected Aby a cam 125, which in turn ispivotally connected to the plate 103. The cam 125 has an inclined slot126 for receiving a pin 127 carried bya slide bar 128. The bar 128 isslidably mounted adjacent to the outer surface of the plate 103.

The forward endof the bar 128 is pivotally connected to one arm of abell crank 129 pivotally kmounted in the plate 103. The other arm ofsaid bell crank is provided with a pin 130 slidably mounted in a groove131 of the horizontal bar 132. The bar 132 is secured to a verticalslide bar 133. Said slide bar is mounted in bearings 134 secured to thesides of the baler. l

The lower end of the bar 133 is provided with i la lug 135 designed torest on a cam 135 carried by the cam shaft 76. Rotatively mountedbeneath the baler frame is a rock shaft 137, each end of which isprovided with a bell crank lever 138. One arm of each lever138 isprovided with ing the tier elements.

a link 139 piv'otauyconnected to the plate 103. The opposite arm of eachbell Crank has a spring 140 so arranged that tension is applied to theplates 163 against rearward movement.

Thust will be seen that as the division blocks move rearwardly throughthe baling chambe;

the shafts 38 and-39 will engage the forward' edges of the dogs 115, asshown by dotted lines in Figure and any further rearward movement or"the division blocks will cause plates 103 to move rearwardly and tensionto` be ap plied to the springs 140.

By this arrangement it will be` seen that a portion of the pressureapplied to thev bale within the baling chamber-will be carried by thedivision blocks and resistance to its movement through the baler will beoffered-by the dogs 115, the toggle joints 121, the plate 163, the bellcranks 188, the link 139 and the spring 146. VAs

the plates 163 move rearwardly, the pins 130 y oredeterniined rearwardposition of its movement. i f

Each ofthe platesv 141 is provided with a pin 142, shown in Figure 1,`designedto pass through the corresponding slots 36a ofthe side members 21.

Each of the pins 142 is mounted in a link 143, said links beingconnected to a-lever I144. "Said levers are pivotally connected to themain `frame 1.6, and have downwardly extending portions 145, each ofwhich is provided with a roller 146 for operating in the cam groove 147on the inner face of the cam plate 148 formed integral with the gear 83,see Figure 41.

The parts are so arranged that as the cam plate 148 is rotated, thelever 144 `will' be oscillated and the plates 141 moved to open orclosedpositions. plates are moved to their closed positions while the balingoperation takes place and moved to their open positions just before thetying mechanism is set into operation'. Y

The method of tying and the mechanism for performing the tying operationmay be more easily described and understood by iirst describing in ageneral way the tying operation. Referenc is made to Figures45to'49`inclusive. y

Mounted opposite the opening 29 is a movable member which I shall termthe primary tier frame 149, and opposite the opening 28 is a tier .trame156. Each tier frame is designed to move into and out of thefeedrchamber throughsaid openings. Adjacent to each of the openings 28and 29 is a wire kguide 151, for the purpose of guiding the wire ashereinafter rnade clear.

The secondary tier frame 150 is provided with a pair of wire clamps 152adapted to clamp and hold one end of the wire 153, said wire extending`across the feed chamber and through suitable openings in the inner endof the primary tier kthe primary tierffrarne 149.

Theswires are forced rearwardly into the wire receiving 'groovesV36 of the division blocks by the rclosing movement of the vplates 141.The material is then fed into the baling chamber and the` wire caused tomove rearwardly with the division block, in the manner illustrated inFigures and 46, with the said wires 153 traveling in` the slots v30 ofthe baling chamber.

The frame members 149 and 150 are then moved inwardly to the positionshown in Figure 49, wLi-h a portion of the free end'of the wireoverlapping a portion of the opposite end of the wire.

@nerend of the shaft 162 is. provided With"a bevel gear 164 designed tomesh with the bevel .167 is rotatively mounted in asuitable bearing 168carried by the main Vframe of the-baler. The

.inner endv of the` shaft 167 has a bevel gear169 in mesh with the bevelgear 170 mounted onthe upper end of a vertical shaft 171. Said shaft5171 has a bevel gear 172 on its lower end, see Figure 1. Said. gear172is in me'shfwith a bevel gear 173 mounted on the inner end oi 'a' sleeve174 rotatively mounted on the shaft 76, which in turnis rotativelymounted kin a sleeve 175 mounted in suitable bearings 176. Theforwardend of the sleeve 174 is provided with a pinion l''designed tocoact with a mutilated gear .178 on. the cam plate 148, while theforward end of the shaft 76 is provided with a1 pinion 179 designedtoicoact with a Ymutilated' gear 189 carried by they plate 148. Thesleeve' 175 is providedV with a cam 181 designed to coact with a lug182carried by the cam plate 148, while the sameisleeve 175 is providedwith a cam 183 designed to coact with a lug 184 to cause thesaid sleeve175fto be rocked, as hereinafter' more fully describe f i f The innerend ofthe sleeve 175 is provided with a segmental sprocket wheel 185,Vsee Figuresl 1, 4 and 15; "Saidhsprocket 185 is provided withz a chain186 designed to operate on a sprocket pinion .187 carried byV a shortshaft 188 and rotatively mounted in a suitable bearing beneath the track156.-

. AThe shaft 188 is provided with a sprocket 189 vgear 165 carried bysuitable bearings 166. The i designed to carry a sprocket chain 190which passes transversely beneath the baling chamber and operates over asprocket 191, carried by a suitable bracket 192, which in turn issupported by a laterally extending frame 193 from the opposite side ofthe baler. The primary tier framev 149 is provided with a downwardlyextending arm 194, the lower end of which is attached to the lower runof the chain 190.

The segmental sprocket 185 is substantially four times the diameter ofthe sprocket 187, so that a rocking movement of the sleeve 175 throughan angle of substantially 90 will impart one 1 revolution to thesprocket 189, and the run of the chain 190 moved a suiiicient distanceto carry the inner end of the tier frame r149 substantially two-thirdsthe distance into the feed chamber to the position shown in Figure 49. ff

It will be seen that as the camplate 148 is rotated, the lug 184willengage the cam 183, see Figure 41, and cause the cam 183 to berotated in amanti-clockwise direction as shown in Figure 41, until thelug 148 passes `beneath the cam 183. This .will cause the cam 181 to bemoved inwardly into the path of thelug 182, and the lower run of thechain 190 moved inwardly and with it the tier frame 149.

A further rotation ofthe cam 148 will cause the lug,182 to engage thecam 181-and the sleeve 175 rocked in the opposite direction, and in turna reverse movement imparted to the Vchain 190 and the frame 149. Areverse movement of the sleeve 175 takes place on account of the cam 181being supported from one side of the center of the plate 148, while thecam 183 is supported from-the opposite side of the center, asillustrated in Figure 1. f

The mechanism just described provides means vwhereby the primary frame149 may be moved ary frame 150 into and out of the baling cham- Saidsecondary frame is provided with a ber. downwardly extending arm 195,-which makes connection with the upper run of the chain 190, asclearlyshown in Figures 1 and 20. The said secondary frame 150 isslidably mounted in the frame member 193.

It will further be seen that the gear 165 will be moved longitudinallyof the shaft 167 as the frame member 149 is moved inwardly andoutwardly, and that rotation may be imparted to the cam 163, while saidframe member is being moved inwardly and outwardly.

'Ihe inner end of the frame member 149 is pro vided with a pair ofinwardly projecting members 196, each of which is provided with a wirereceiving opening 197. The front` face of each of the members 196 isprovided with a roller 198, which serves as a wire guide, while the backface of each of the members 196 is provided with rearwardly extendingbrackets 199 having rollers 200 which' act as wire guides, the wirebeing threaded through the openings 197 and carried by the reels 201,hereinafter described in detail.

Secured vto the rear face ofthe inner end of the frame 149 is a. pair ofbrackets 202, each of which is provided with a central opening 203 inwhich is mounted a twisting mechanism, which is as follows, see Figures26 to 32 inclusive, and

also Figure 7.

The center of the openings 203 are spaced apart, a distance equal to thespacing of the wires. The rear edges of the brackets 202 are providedwith notches 204 through which the lthe hub within the opening 203, saidplate beingv secured in position by suitable screws 208.

The hub 205 is provided with a slot 209 pro-` rjecting inwardly to thecenter of said hub for receiving wires to be twisted. Adjacent to oneedge of the slot 209 is a clamp plate 210, having laterally projectingmember 211 designed to be supported on a plate 212, by means ofsuitable' screws 213. The plate 212 is provided withslots 214 forreceiving set screws 215 by means of which the plate 212 and the clampplate 210 may be adjustably supported to increase or decrease the widthof the slot 209 for adjusting the device to operate with wires ofvarious diameters.

The opposite edge of the slot 209 is provided with a clamp plate 216,which has a laterally extending portion 217 detachably secured to aslide bar 218 mounted in a suitable groove 219 in the hub 205, wherebythe clamp plate 216 may be moved toward or from the plate 210. The slidebar 218 is provided with a laterally eX- tending lug 220 designed tooperate in a groove 221 in the plate 207. The plate 207 is provided witha pair of lugs 222, between which is pivotal- 1y mounted a lever 223having a knob 224 on its lower end, and a link 225 pivoted to its upperend, said link being pivotally connected to the lug 220, as illustratedin Figures 27 and 28.

It will readily be seen that if the knob 224 is moved toward or from theplate 202, the bar 218 will be moved longitudinally in the slot 219, tocause the plateA 216 to move toward and from the plate 211, and causethe wires to be gripped as they enter the slot 209, after which thesprocket 205 may be rotated and the central portions of the overlappingwires twisted in the manner illustrated in Figure 49.

It will be seen by reference to Figures 27 and 28 that the parts are soarranged that when the member` 216 is moved inwardly toward the member210, the pivot center between the members 223 and the link 225 will lieinside of the pivots of said lever and said link, thus forming a lockfor retaining the clamp plates in a closed positiony during the twistingoperation.

To insure against accidental unlocking, an annular flange 226 isprovided, having a notch 227 for receiving the member 24 when the clampplates are in anvopen position. The free end of the lever 223 isdesigned to ride over the edge of the flange 226, when the clamps are ina closed position, and during the time the rotation of the twistingmember takes place.

The mechanism just ydescribed performs the function Vof the twistingmechanism 155 above referred to.

For rotating the sprockets 206 I have provided a chain 228 designed tooperate over sprockets 229 on the members 202, in the manner illustratedin Figure 7. A pinion 230 is designed to engage the central portion ofthe iront run of said chain, said pinion being mounted on ahorizontalshaft 231 in suitable bearings carried by `the upright plate159. The outer end of the shaft the cam plate 163, see Figure 5.

Thus means is provided whereby the wires may llO be twisted after theyhave been properly placed in the slots 209. The detachable`clampingplates 210 and 216 provide means whereby renewal may be easilyand quickly accomplished on account of excessive wear. f Adjustment isalso provided for adapting the-device to operate with wires of differentdiameters, thereby insuring a perfect twist. This adjustment alsoinsures against wear on the clamping plates.

-For operating the free ends of the levers'223, I have provided a rochshaft 234, see Figure 33, rotatively mounted in suitable bearings in themembers 292. Said rock shaft provided with rock arms 235each of whichhas its free end `forked to receive the knob 224 of levers 222. The arms235 are actuated by a rocking movement of the shaft 234 to swing theknob 224 inwardly or outwardly. rhe upper end of the shaft 284 isprovided with a rock arin 236 connected to a link 237, see Figures 5 and6, the outer end or which is pivotally connected to a bell crank lever228 pivotally mounted on the plate 15,9.

The free end for the lever 226 is provided with a roller 239 designed tooperate in a cam groove 240 in the plate 163. Ihus means is provided foropening and closing the clamping plates of the twisting mechanisinas thecam plate 63 is rotated.

To assist in guiding the wires into the twisting mechanism, and forretaining the free end ofthe wire, after it has been severed from the.A

bale, and for severing saidl wire, I have provided the followingmechanism.

Pivotally mountedto the rear edge of each of the members 262 I haveprovided what I shall term a gate 241. vided with an inwardly Aextendingarm 242, see Figure 7. Said arms 242 are pivotally connected to a link243 having its cuter end carried by an upright link 244. free end of thelink 243 is provided with a roller 245, designed to travel in a camgroove 246 in the plate ,163. Thus means is provided whereby the freeends of the gates 241 may be swung from the position shown in Figure 5to the position shown in Figures 14 and 49, or vice versa.

The free end ci cach of the gates 241 is provided with a cutting andclamping mechanism illustrated in detail in Figures 21 to 25 inclusive.A head 247 is provided at its lower edge with a groove'or recess 248 anda notch 249 in its rear edge.

A slot 250 is provided'in which is slidably mounted a bar 251 having atongue 252 on its lower end designed to be moved into and out ofthe'groove 248, and to travel between lugs 252 carried by the head 247,in such a manner thatwhen the wire 153 is moved into the notch 249 thebar 251 may be elevated and with it the lug 252, causing the wire to begripped in the slot 248. v

Slidably mounted adjacent to the rear face of the head 247 is acutterplate 254, also having a notch 255 for receiving the wire. Thenotches 249 and the notch 255 are in common alinement when the device isin its normal open position with the lug 252 at its lower limit ofmovement.

The'cutter plate 254 is provided with a laterally extending lug 256designed to support a bolt 257 mounted on a spring 258. The vlower endof the bolt 257 is designed to support a lug 259 projecting outwardlyfrom the slide bar 25. so that as the cutter bar 254 is elevated, theslide bar 251 andl the gripping lug v252 will alsobe Each of said gatesis proyieldably elevated. Themember 252 is elevated a slight distance inadvance of the cutting member 260, and the bar 254, so that the wire 153isrmly gripped before the cutting operation takes place. That portion ofthe wire supported in the gripper is connected to the reel, while otherportion of theiwire is carried by the twisted portion. Y l f f Thenieansfor actuating the cutter bar 254 comprises a rock shaft 261pivotally mounted to the outer edge of each of the gates 241, seeFigure-s 5 and 6. One end of the roclzshaft is .provided with laterallyextending portion v262 designed to enter an opening263 in the upper endoi the cutt r plate 254, while the other end of' the rock shaft k261 isprovided with a forwardly extending arm 264 designed to travel in aslotted curved plate 265, which is slidably mounted '268 which havetheir ends connected to a coininon slide bar 269, slidably mountedadjacent to the inner face of the bar 243, having its free end carriedby an upright link 270. Said slide bar 269 is provided with a roller 271designed to .travel in a cam groove 272 of the plate 163.

I will now describe theconstruction of the secondary tier frame, whichcomprises a plate 273 slidably mounted in bearings 274 carried by thefreine 198. The forward end of the plate 273 is provided with a hingemember forming what yI shall term a wire threader and designated by thenumeral 275, see Figures 36, 37, 38 and 39.

The said threader is formed oi a plate provided with hinges 277, bywhich the threader is hinged to the plate 273. Said plate 275 isprovided with horizontal grooves 278 and a vertical groove 279connecting the outer ends of the grooves 278.

The groove 279 is provided with a pair of'clamping bars 280, each ofwhich is provided at itsk outer end with a-laterally and inwardlyextending portion 281, said portions being designed .to enter grooves282 in the upper and lower edges or" the member 275. The members 281 aredesignedl to project above the upper and lower edges of the member 275,as illustrated in Figure 36, to form :wire receiving slots 283,andadapted toy receive the wire 153 in the manner hereinafter 'fully setforth, and to clamp and grip the wire as the bars 280 are moved inwardlytoward each other, in the manner illustrated in Figure 29. The members281,. and 282 forni the clamping devices 152 before referred to. Y

Pivotally mounted in each or the slots 272 is a lever 284, the outerends of which are pivotally connected to the 'oars 288 and have theirinner ends pivotally connected to the horizontal armsfof the bell cranklevers 285. Said levers in turn are pivotally mounted on the inner end.of the plate 278 and have their other ends overlapping and pivotallymounted vto a pivot member 286 carriedy in unison and the lever 284operated, which in,

turn will cause the bars 289 to be moved inwardly or outwardly to clampor release the wires. The

pivotal connection between the members 284 and the members 235 ismounted in the pivot axis of the member 275, so that the clamp members281 may be actuated when the bar 275 is in any of its swinging positionsof movement.

A cover plate 239` is provided for the member 275, which retains themembers 280 slidably in the groove 279 and covers the slots 278. Theplate 289 is rigidly supported in position.

The outer face of the plate 289 is provided with a lug 290 connected toa link 291, which in turn is connected to a lug 292 carried by the slidebar 293, also mounted in the guides 288 outside of the slide bar 287.

Y It will be seen that if the bar 293 is moved longitudinally, themember 275 may be swung from the position in alinement with the frame273,

as illustrated in Figure 37, to a.` position substantially at rightangles tosaid frame, as illustrated in Figures 14 and 49.

For imparting movement to the slide bars 287 and 293, I have providedbeneath the bottom of the baling chamber a pair of rock shafts 294 and295, see Figures 4, 14, 15 and 20. The rock shaft 294 is provided withdownwardly extending arm 296, having a cam roller 297 designed tooperate in a cam groove 298 carried by the cam 299 supported on the camshaft 76, so arranged that as said cam shaft 76 is rotated, rockingmovement will be imparted to the shaft 294.

In a similar manner the shaft 295 is provided with an arm 300 having aroller 301 designed to operate in a cam groove 302 of a cam 303, alsocarried by the shaft 76.

Thev shaft 294 is provided with a pairof forwardly extending arms 304designed to support a shaft 305 between them. Said shaft 305 is slidablymounted in the lower end of a vertical link 306, having its upper endpivotally connected to a bell crank lever 307, one arm of which ispivotally kconnected with the slide bar 287, see Figure 20.

By this arrangement it will be seen that a rocking movement of the shaft294 will cause the link 336 to be elevated or lowered, and the bar 287to be reciprocated longitudinally. 7

In a like manner the shaft 295 is provided with a pair of forwardlyextending arms 308 connected by a rod 309 slidably mounted in the lowerend of a link 310, which in turn has its upper' end pivotally connectedto a bell crank 311, one arm of which is pivotally connected with theslide bar 293. Thus means is provided whereby the threader head may beswung about its vertical axis by rocking the shaft 295.

It will be seen that both the head 275 and the clamping device 152 maybe actuated when the frame member 150 is in any of its sliding positionsof movement, as the links 306 and 310 are free to slide on the shafts305 and 309.

Both of the bell crank levers 307 and 311 are mounted on a single pivotpin 312 carried by the downwardly extending arm 195, both of said linksbeing pivotally connected to a pair of horizontal links 313, which arealso pivoted to the member 195. 310 against lateral movement due tofrictional Contact between said links and the rock shaft as the framemember 150 is moved inwardly or outwardly.

I will now describe the wire guides 151 above referred to, see Figures34, 35, 15 and 16.

Each of the 'saidwire guidesy comprises a frame The links `313 supportthe members 306 andV ally extending legs 320 spaced apart and eachpro-f.

vided with an opening 321 in which is rotatively mounted a sleeve 322.The inner ends of the sleeves are provided with detachable collars 323and the outer ends of the sleeves are provided with convex heads 324.Said sleeves are rota-fA tively mounted in the legs. Each of the sleeveshas a slidable mounted pin 325. The inner ends of the pins are providedwith grooves 326.

' A lever 327 is pivotally connected in the groove 326 of the upper pin325, said lever in turnY being pivotally connected to the frame 314,which in turn is pivotally mounted to the slide rod 323, slidablymounted in the pivot member 316 and slidably mounted in the lower end ofthe pivot member 315. A spring 329 is provided forv yieldably supportingthev rod 328 at its lower limit of movement. The upper end of the lowerpin 325 is pivotally connected with an arm 330 rigidly supported on theshaft 328.

By this arrangement it will be seen that if the rod 328 is elevated orlowered, the lower pin y325 will move in unison and in the samedirection as the rod 323, while the upper pin 25 will be operated in theopposite direction, due to the fact that the lever 327 is pivotallymounted to the frame 314.

Detachably secured to each end of the frame 314 is a leg 331, each ofwhich is provided with a sleeve 332 similar vto the sleeves 322, withthe exception that the sleeves are arranged in opposite directions, sothat the heads 324 are adjacent and spaced a slight distance apart. Thelast said sleeves are designed to receive the outer ends of the pins 325when the bar 328 is at its lower limit of movement and thereby close theloop portion 333 formed by the inner and outer legs. Said loops arespaced apart a distance equal to the spacing of the wires, so that asthe wire guides are swung on their pivots, they may be made to receivethe Wires within the loops 333, when in one position of their movement,after which the said loops are closed and then by swinging the guides,the wires may be moved to another position for the purpose of deliveringsame to the twister and for guiding the wires.

The lower end of each of the members 316 is provided with a laterallyextending arm 334, one of said arms extending forwardly, and the otherone rearwardly, and are connected by means of a link 335, see Figure 15.The forwardly extending arm 334 is provided with a rearwardly extendingportion 336 to which a link 337 is connected, said link being pivotallyconnected to a loop member 338 slidably mounted on the shaft 76 andadjacent to a cam 339. The loop 338 is provided with a cam roller 340designed to be actuated by the cam 339, so that longitudinal movementwill be imparted to the link 335, and rockingy movement imparted to theguide frames 314. Said frames are adapted to move into and out of thefeed chamber.

Supported below the bottom of the baling chamber and adjacent to theshaft 294 is a rock shaft 341 having a downwardly extending arm 342designed to operate` on a cam face 343 of the cam 299. Said shaft 341 isprovided with an arm 344 which projects forwardly and'is designed toengage the lower end of the rod 328.

v vThus lmeans is provided whereby the rod 328 may be elevated andlowered, and the wire guide clampsopened and closed when the member 314is in, an;T of its swinging positions of movement. In order to providemeans whereby the wire may be fed at a comparatively uniform tension, Ihave provided the wire reels 201, each of which comprises a cylindricalmember 345, having at one edge an outwardly projecting flange 346.-

One edge of the member 345 is detachably secured to the inner edge `ofan annular member 347, by means of Y suitable fastening devices 348. Theouter edge of the member 347 is provided with an inwardly extendingflange portion 349 terminating in an outwardly extending flange 350. Theouter face of the flange 346 is designed to support an annular member351, having an inwardly extending flange 352 terminating in an outwardlyextending flange 353 supported adjacent to the flange 350.

The member 351` is slidably mounted on bolts 354 and yieldably retainedat its inner limit of movement by means of springs 355, so that theflanges 350 and 353 are yieldably supported adjacent to each other. Themembers 345, 350, and 352 are spaced apart to form a chamber forreceiving the coil 356 of the wire 153. .The Wire 153 is designed topass outwardly between the flanges 350 and 353. Each of the members 345is hung on an arm 357 supported bythe main frame of the baler. SeeFigure 1.

Thus it will be seen that as the wire is pulled outwardly, the lowersides of the members 201 will be swung rearwardly and rotated on lthemembers 357. The said members 201 always tend to assume a position withtheir most eccentric portions immediately below the arms 357, While themovement of the wire as it is fed to the tying member will have atendency to swing said eccentric points rearwardly and to a somewhatelevated position, thereby providing yieldable means for taking up slackin the wire, due to the outward movement of the tier frames.

The practical operation of, my device is as follows:

Assuming that a bale has been completed, as shown in `Figure 45, andthat the shafts 38 and 39 of the division block 35 have engaged theforward ends of the1dogs 115, and that the plate 103 Vhas been movedrearwardly until the angle 102 has engaged the lower end of the arm 100,

and that the said arm has been swung rearwardly,

causing the rod 99 to be'moved rearwardly, which in turnwill cause thetrip plate 95 lto be Amoved rearwardly and to disengage the lug 98 ofthe cam 148, which in turn will cause the lug 87 to be forced againstthe outer face of the hub through the tension of the spring 93. As soonas the plunger 25 has moved to its rearward position ofv movement, thenotch 36 will be in position to receivefthe lug 87, causing the gearwheel 84 to be rotated 'in unison with the shaft 19.

In actual operation the ratio vbetween the 'gears 83 and 84 ispreferably three to one, so

that the crank shaft 19 will make three complete revolutions during thetime thecam 148 makes one revolution.

v The arrangement of the mutilated gears k178 and 180, and the lugs 82and 84 on the cam 148, is such that approximately four and one-halfstrokes of the plunger will take' place before the said mutilated gearsor lugs move to position to operate on'their coacting members, it beingunderstood that three revolutions of the crank 19 will produce sixplunger strokes.

During the first stroke of the plunger after the cam is set intooperation the feeding mechanism is stopped and the material from thefeeder and baler severed, as fully described in my copending applicationon Feeder for baling presses, flied May 28, 1929, Serial Number366,684.v `The next two inward strokesA are for the purpose of cleanngthe feed chamber. i g Slightly after the beginning ofA the third-forwardstroke, the mutilated gear 180 will engage the pinion 179, Figurel 1showing thecam` 148 in last said position.r This will cause thecam shaft76 to be rotated, and at the same time movement is imparted `to thelever 144, causing the plates 141 to be lwithdrawn from coveringy theopenings 28 and 29.` i v The cam 339 will then impart inward movement totherod 337,v which will cause the guide members 151 to be moved inwardlyinto the feed chamber, to substantially the position shown by dottedlines in Figure 45, with loops 333. `The rock arm 300 is then actuatedby the cam 302, causing the bar 293 to be moved inwardly and thethreader head 275 rto be moved into alinement with the bar 273. The lug184 will then engage the-cam 183, and cause the sleeve` 175 to be rockedandl the primary and secondary tier `frames to bemovedinto the feedchamber.

The threader head 275 is again kswung forwardly and back of the tiermechanism 155, as'illustrated in Figure 48. `The pins 325 of the guidedevice are then moved to their closed position, so that the wires 153are locked in the loop portions 333. v f

The guide devices 151 are then moved-outward,- ly to swingthe wires 153to a'parallel position with portions overlapping, as indicated in Figure44, causing the overlapping portions'of the Wires to enter the 'grooves204 and 209 of the twisting mechanism. The mutilated gear 178 at thistime engages the piniongear 177,` causing the sleeve 1'74'to be rotated,and with it the cam '163 through the bevel gears-172, 173, 169, 170, 164and 165, and their connecting shafts; The rotation of the cam 163 willfirst cause the bell crank 238 to be operated as' the said` cam isrotated `in an anti-clockwise direction, as illus- `trated in Figure 6,causing the link 237 to be operated andin turn the rock shaft 234, whichwill cause the clamping plates 210 and 216 to be closed through thelever mechanism 223, and the overlappingportions of the wires 153 to begripped at their central portions. The mutilated gear 233 of the cam 163is then brought into engagement with the pinion 232. causing the twistersprocket 206 to be rotated through the chain 228, the pinion 230 and theshaft 231. The free 'ends of the'overlapping wires are at this timerigidly Yclamped between the member 281 and the grooves 42800i themember 275', while the loop portion ofv the wire rests in the notches249 carried by the head v247. The gates 241 at this time are swung totheir forward position of movement, as illustrated in Figure 44, insucha manner that the ends of the overlapping portions are rigidly heldduring the time the twister is in operation.

After the twisting operationV has taken place, the 'slide bar 269 isoperated by the roller 271 travelingin the 'cam groove 272, causing theplates 265 to be lowered and the cutter bars 254 to be elevated, causingthat portion of the wire lyingin the groove 249 of the head 247 to begripped, and the twisted portion of the wire to be severed from thegripped portion.

VThe'roclr shaft 234 is again operated and the pressure released betweenthe gripping plates 210 and 216. At the Sametime the members 281 aremovedoutwardly to release the wire gripped thereby. The pins 32,5 arealso withdrawn to open the loops 333. l It will then be seen that thetying operation of the wire has been completed, and the loop portion ofthe wire released from all of the gripping mechanism.

It will further be seen that a considerable space will remain betweenthe twisted ends and the front endof the bale, which will result in aconsiderable' amount of slack in the wire.

At this period in the operation the cam 136 engages the lug 135,causi`ngthe member 133 to be elevated, the bell crank 129 operated, the bar 128moved longitudinally, and the link 124 lowered, causing the dogs 115 tobe released from the shafts 38 and 39. This will then permit the bale toexpand and the division block moved rearwardly, which will then drawtheslack 4out of the newly tied wires, and the twisted ends-of thewires-to iirmly engage the forward end ofthe bale. This leaves the feedchamber back of the tier mechanism entirely free fromfany loose or slackwires.

' The forward movement of the plate 103 will cause the member 102 todisengage the arm 100 but the' clutch memberis still retained in itsclosed position due to the action of the spring 93.

The'link 243 is at this time operated by means oi' the roller 245traveling in the groove 246, which will cause Vthe gates 241 to be swungrearwardly in a plane substantially parallel with the plate 149. Thegripping mechanism of the head 247 still retains 'the lfree end of the(cut wire. The wires are then` drawn rearwardly in such a manner thatthey will be brought into alinement with the grooves or notches 283 ofthel head 2'75, assuming the positionillustrated in Figure 33.

The rtier frames are then moved outwardly on account of the lug182'engaging the cam 181 and reversing the movement of the chain 190.'This will cause the wires supported by thehead 247 56 to enter thenotches 283, after which' the bars 280 are againmoved inwardly and thecutter plate 254 movedy downwardly, releasing the wire from the head247, said wires being pulled out of the notches 249 and the tier framesreturned l'to their outer limits of movement. The guidesV 151 are alsoreturned to their normal positions of movement, as illustrated in Figure14, with the wires projecting laterally across the feed chamber,

`which are at all times kept taut due to the swinging movement of thewire reels as above described. The cam at this time engages the roller79 causing the arms 71 to be swung'downwardly and a new block to bepushed into position within the slots 31. vThe plates `141'are thenmoved rearwardly, causing the wires` to be'moved from the positionillustrated in Figure 14, to position within the grooves 36 of the block35.

The feeder is then sety into operation through mechanism'carried by theinner end of thecam shaft 82. 'Ihe lug 98' of the cam'148 will thenengage the cam surface 96 of the member 95, causing the arm 89 to beswung outwardly and the lug 87 to be withdrawn from the notch 86, as thesaid lug 98 engages the face97, after which the mechanism is in itsnormal position ready to 'receive a new bale..

Thus it will be seenthat I have provided a baler having means wherebythe division blocks will be automatically placed in position and willbelocked imposition against upward movement, clue to the action of thecompressed hay against the block, and at the same time providing meansfor automatically returning the block to its forward position ofmovement, where it is held in position to be lowered when the tyingoperation has been completed. This mechanism is automatically controlledand operated.

It will further be seen that I have provided means for automaticallyplacing wires around and tying or twisting the same, and in connectiontherewith means whereby the slack will be taken out of the wires afterthey have been twisted, so that slack wire is completely withdrawn fromthe feed chamber, where it will not interfere with the placing of thenew'blockin position or become tangled on the various devices as the.bale is moved through the baler.

It will further be seen that the twisted portion of the tie comes midwaybetween the sides of one end of the baler where the strain on the wire,and'its tendency to untwist, are the least.

It will further be seen that I have provided an improved auxiliarytension device which' may be used in connection with the ordinarytension'devise, which performs the double function of setting into andout of operation the various mechanisms for performing the feeding andtying operations, and at the same time providing means for taking upslack in the newly tied wires.

It will further be seen that I have provided an improved twistingmechanism which is adapted to be adjusted against wear, so that thewires are always firmly and positively gripped before the twistingoperation takes place, and thereby insuring a complete twisted tie, andat the same time providing means for adjusting the device to wires ofvarious diameters,v

Means is valso provided for taking up the slack vwire as itis fed to thetying mechanism,rand as it is drawn to position around the bales as theyare being formed. K AI claim as my invention:
